Dynamically generating sharing boundaries

ABSTRACT

A collaboration system provides network access to a plurality of content objects. The collaboration system facilitates collaboration interactions between particular users by allowing or denying network access to the plurality of content objects based on user invitations. A computing module observes and records user-to-user or user-to-content collaboration invitations over the plurality of content objects. On an ongoing basis, a collaboration network graph is constructed and maintained, with updates to the collaboration network graph being continually applied based on observed collaboration interactions. On demand, such as upon receipt of a user request for access to a content object, the updated collaboration network graph is consulted so as to generate a then-current sharing boundary. If the user that raised the user request is within the generated then-current sharing boundary, then access to the content object is granted, otherwise further processing is invoked to determine if the user should nevertheless be granted access.

FIELD

This disclosure relates to collaboration systems, and more particularly to techniques for dynamically generating sharing boundaries.

BACKGROUND

In modern collaboration systems, a large portion of the collaboration activity involves users sharing certain content objects with other users. In many systems, users share a content object by distributing a link (e.g., hyperlink, weblink, etc.) to the content object rather than distributing the actual content object. When a user receives such a link at a user device and follows (e.g., clicks on) the link, an application (e.g., web browser or web-enabled function) at the user device is directed to a resource location at the collaboration system. The collaboration system in turn checks the user's credentials and, if the user is provisioned sufficient access rights, then access to the content object is granted. Such access might invoke a download of the content object, or a preview of the content object, to the user device of the user.

Users today demand that collaboration systems offer certain predefined access models to make content object sharing convenient and efficient. As examples, such access models might facilitate a user sharing a content object with (1) any user who is on a particular collaboration list (e.g., as specified by the user), (2) any user who authenticates with a particular domain (e.g., “CompanyName.com”) or, (3) any user who has the link.

While the sharing boundary of the first two example models is strictly defined (e.g., by the collaboration list and the domain), the sharing boundary of the latter model is uncertain. Specifically, in this latter case, it is possible that a legitimate, intended recipient (e.g., a user to whom the sender intended to receive a link) might forward the link to an unintended recipient. For example, the sender may have used the unrestricted link sharing model in error or may have expected the recipients to abstain from not forwarding the link. Even the other aforementioned access models can be misused. As examples, a user might inadvertently add (e.g., typo, type-ahead error, wrong name, etc.) one or more unintended recipients to a collaboration list or select a wrong (e.g., unintended) domain.

Unfortunately, there is no mechanism in today's collaboration systems for detecting and remediating such unintended content object sharing events. The lack of such a mechanism can be extremely costly to an enterprise or even individual users. For example, a CEO who sends a document intended for only his or her staff to the entire organization, or worse, to recipients outside the organization, can suffer severe consequences. In many cases, the user (e.g., document owner) who first shared a content object may not even know that the content object was accessed by unintended recipients. What is needed is a way to detect and remediate unintended access to content objects by users in a collaboration system.

DETAILED DESCRIPTION

Aspects of the present disclosure solve problems associated with using computer systems for unintended access to content objects by users in a collaboration system. These problems are unique to, and may have been created by, various computer-implemented methods used in collaboration systems. Some embodiments are directed to approaches for consulting actively-updated collaboration network graphs to determine the sharing boundaries of content objects. The accompanying figures and discussions herein present example environments, systems, methods, and computer program products for dynamic generation of sharing boundaries.

Overview

Disclosed herein are techniques for consulting actively-updated collaboration network graphs to determine the sharing bounds of content objects. In certain embodiments, collaboration interaction events (e.g., user-to-content collaboration interactions, user-to-user collaboration interactions, etc.) at a collaboration system are actively monitored and processed to generate the collaboration network graphs. As used herein, a collaboration network graph is a logical representation (e.g., involving one or more data structures) of the entities (e.g., users, content objects, etc.) of a collaboration system and their relationships between such entities. When a collaboration network graph is implemented as nodes and edges between nodes, the nodes correspond to entities and the edges correspond to relationships between any two entities. Some implementations of a collaboration network graph characterize relationship strengths between a particular subject user and various other users. The relationship strength can be characterized as a relationship type and/or a relationship magnitude. Relationship strengths can also be characterized by degrees of separation between two entities.

When a particular subject user (e.g., content object owner) identifies a content object for sharing, a then-current instance of a collaboration network graph is accessed to determine a sharing boundary for the particular subject user. Subsequent to the sharing, and responsive to the act of another user's requested access of the shared content object, the then-current sharing boundary is consulted. The then-current sharing boundary is used to determine which other users are able to access the content object. If access to a content object by a suspect recipient is detected (e.g., a user whose user node in the collaboration network graph is outside of the sharing boundary), an alert is issued to the subject user (e.g., the sharer). An updated sharing boundary is then generated based at least in part on the response to the alert from the subject user.

For example, the subject user might allow the suspect recipient to access the content object, thereby expanding the sharing boundary to an updated sharing boundary that includes at least the suspect recipient. In certain embodiments, the updated sharing boundary might include other users that share certain user attributes (e.g., department, email domain, etc.) with the suspect recipient. In certain embodiments, the sharing boundary is based at least in part on a number of degrees of separation the users within the boundary are from the subject user (e.g., as indicated by the then-current collaboration network graph). In certain embodiments, the sharing boundary is based at least in part on a rule base (e.g., a policy). In certain embodiments the collaboration network graph and/or the sharing boundary are actively updated in response to the detection of the user interaction events and/or other non-interaction data. In certain embodiments, the sharing boundary is dynamically updated based on a relationship between a user requesting access and other users, such as users in the same cohort of another enterprise.

Descriptions of Example Embodiments

FIG. 1 illustrates a computing environment 100 in which embodiments of the present disclosure can be implemented. As an option, one or more variations of computing environment 100 or any aspect thereof may be implemented in the context of the architecture and functionality of the embodiments described herein.

FIG. 1 illustrates aspects pertaining to consulting actively-updated collaboration network graphs to determine the sharing boundaries of content objects. Specifically, the figure presents a logical depiction of how the herein disclosed techniques can be used in a computing environment to dynamically generate sharing boundaries to prevent unintended access to content objects by users in a collaboration system.

The logical depiction of FIG. 1 illustrates a selected set of users (e.g., user “u1”, user “u2”, user “u3”, user “u4”, and user “u5”) from a plurality of users 102 in a collaboration system 110 that interact with each other through instances of user-to-user interactions 114. For example, a first user might raise a sharing invitation to a second user to collaborate on some task, and/or might raise multiple sharing invitations that comprise requests to join a group of other users. A user-to-user interaction may also be based on an implicit user-to-user relationships (e.g., based on organizational structures). Any of users 102 might also invoke certain instances of user-to-content interactions 112 with various instances of content objects 106 (e.g., folder “/fA”, file “f1”, folder “/fB”, file “f2”, and file “f3”). As an example, a first user might create a document and then share the document with other users for viewing, editing, or commenting on by the other users. For a user-to-user interaction, the collaboration “entities” are both users, whereas for a user-to-content interaction, the entities include a user and a content object.

In modern collaboration systems, such as collaboration system 110, users 102 might share content objects by distributing links (e.g., hyperlinks, weblinks, etc.) to the content objects rather than distributing the actual content objects. When a user receives such a link at a user device and follows (e.g., clicks on) the link, an application (e.g., web browser or web-enabled function) at the user device is directed to a resource location at collaboration system 110. Collaboration system 110 in turn checks the user's credentials, and if the user is provisioned sufficient access rights, then access to the content object is granted or allowed. Such access might invoke a download of the content object or a preview of the content object to the user device of the user.

Various predefined access models exist to facilitate efficient sharing of content objects. As examples, such access models might facilitate a user sharing a content object with any user who (1) is on a particular collaboration list (e.g., as specified by the user), (2) authenticates with a particular domain (e.g., “CompanyName.com”) or, (3) has a link to a content object. While the sharing boundary of the first two example models is strictly defined (e.g., by the collaboration list and the domain), the sharing boundary of the latter model is uncertain. Specifically, and in this latter case, it is possible that a legitimate, intended recipient (e.g., a user to whom the sender intended to receive a link) might forward the link to an unintended recipient.

The herein disclosed techniques address the problems attendant to such unintended access to content objects by consulting actively-updated collaboration network graphs to determine the sharing boundaries of the content objects. The dynamically-generated sharing boundaries are analyzed to allow or deny access to users requesting the content objects. Specifically, and as shown in computing environment 100, various user interaction events associated with user-to-content interactions 112 and user-to-user interactions 114 are actively monitored at collaboration system 110 (operation 1). User interaction events are processed to construct one or more collaboration network graphs associated with users 102 and content objects 106 (operation 2).

A collaboration network graph, as used herein, is a logical representation (e.g., graph) of entities (e.g., users, content objects, etc.) of a collaboration system and their relationships. The nodes of the collaboration network graph correspond to the entities and the edges of the collaboration network graph correspond to the entity relationships. One implementation of a collaboration network graph might characterize the relationship strength (e.g., degree of separation) between a particular subject user and various other users (e.g., collaborators). As an example, at a first moment in time, a set of user interaction events 116 ₁ might be analyzed to construct a collaboration network graph 122 ₁ that pertains to a particular user.

Sharing boundaries associated with the collaboration network graphs are generated (operation 3). As can be observed, a sharing boundary 124 ₁ associated with collaboration network graph 122 ₁ is generated. As representative of merely one example, sharing boundary 124 ₁ is shown as a contour over the collaboration network graph that subsumes a set of users. In this example, the sharing boundary depicts that only certain users who are only at one degree of separation from a subject user might be allowed access to various content objects owned by the subject user.

In this case, the owner may have issued instances of content owner directives 126 ₁ that state that users within one degree of separation, as determined by the then-current collaboration network graph (e.g., collaboration network graph 122 ₁), are to be included in sharing boundary 124 ₁. As used herein, such content owner directives comprise information from content owners or representative of content owners (e.g., an enterprise system administrator) that serves to define the constraints (e.g., permissions) pertaining to access of the content objects. As an example, content owner directives might be captured at a user interface and codified (e.g., as attributes, as parameters, as logic, etc.) into certain sharing policies or access rules. As later discussed, content owner directives may be derived from responses to access request alerts that are issued to content owners.

At a second moment in time, additional user interaction events (e.g., user interaction events 116 _(K)) are processed to facilitate construction of an updated collaboration network graph such as is depicted in collaboration network graph 122 _(K). As shown, entities are added to collaboration network graph 122 ₁ to form collaboration network graph 122 _(K). The content owner directives (e.g., content owner directives 126 _(K)) issued by the subject user associated with collaboration network graph 122 _(K) results in the shown sharing boundary 124 _(K). Specifically, and as depicted in this example, content owner directives 126 _(K) may have denied all content object access requests issued by users (e.g., unintended recipients of a sharing URL) beyond one degree of separation.

In other cases, however, the sharing boundaries are updated based at least in part on input from the content object owners (operation 4). As shown, at some third moment in time, instances of content owner directives 126 _(N) may cause an update to the sharing boundary associated with collaboration network graph 122 _(K), which updates result in the sharing boundary 124 _(N) as depicted within collaboration network graph 122 _(N). Specifically, and as can be observed, sharing boundary 124 _(N) includes users that are at one degree of separation from the subject user as well as three other users that are at two degrees of separation from the subject user. Continuing this example, if the three users have been explicitly allowed (e.g., by the owner) to gain access to the requested content objects, that explicit allowance expands the sharing boundary to include those three additional users. Granting access to a particular one or more users that are at two degrees of separation from the subject user does not automatically imply that all users at two degrees of separation from the subject are granted access.

As another example, the sharing boundary may have been updated to include the three users due to certain user attributes (e.g., department, email domain, etc.) that are shared by the users. Moreover, the consistency between the collaboration network graphs at this third moment and the earlier mentioned second moment in time indicate that additional user interaction events (e.g., user interaction events 116 _(N)) did not affect the structure and/or constituency of the collaboration network graph even though the sharing boundary was updated to include the three additional users.

In any case, the dynamically-generated sharing boundaries that are overlaid onto the actively-updated collaboration network graphs serve to address the problems attendant to unintended provisioning of access to content objects by users in a collaboration system. As such, application of the techniques disclosed herein facilitate improvements in computer functionality. Specifically, consumption of such computing resources to maintain and use more rigid access models (e.g., hard-coded permissions, digital rights management, etc.) is eliminated at the same time that application of the techniques disclosed herein offer greater flexibility when sharing content objects among collaborators.

One embodiment of techniques for ongoing management of such dynamically-generated sharing boundaries is disclosed in further detail as follows.

FIG. 2 depicts a sharing boundary management technique 200 as implemented in systems that perform dynamic generation of sharing boundaries. As an option, one or more variations of sharing boundary management technique 200 or any aspect thereof may be implemented in the context of the architecture and functionality of the embodiments described herein. The sharing boundary management technique 200 or any aspect thereof may be implemented in any environment.

FIG. 2 illustrates aspects pertaining to consulting actively-updated collaboration network graphs to determine the sharing boundaries of content objects. Specifically, the figure is presented to illustrate one embodiment of certain steps and/or operations performed over various devices (e.g., user devices, servers, systems, etc.) to dynamically manage access to a large number of content objects by a large number of users in a highly collaborative shared content management system. As can be observed, a certain portion of the steps and/or operations can be characterized as dynamic operations 210.

The sharing boundary management technique 200 commences by configuring a collaboration system that facilitates interactions over a plurality of users and a plurality of content objects managed by the system (step 220). As earlier described, such interactions comprise user-to-content interactions and user-to-user interactions, and can be characterized as discrete user interaction events. Continuous monitoring of such user interaction events between the user and the content objects is performed at the system (step 230). As shown, the monitoring might result in a set of user interaction events 116 _(M) at some moment in time.

A then-current set of user interaction events are analyzed to construct one or more collaboration network graphs (step 240). For example, user interaction events 116 _(M) might be analyzed to produce a set of collaboration network graphs 122. Since monitoring of user interaction events (step 230) and ongoing construction of the collaboration network graphs from user interaction events (step 240) are dynamic operations 210, the collaboration graphs are actively-updated and made accessible for use in accordance with the herein disclosed techniques. In some implementations, collaboration network graphs are user-centric. In such implementations, the collaboration network graphs characterize the relationship strengths (e.g., degrees of separation) between a particular subject user and various other users (e.g., collaborators) as being derived from the then-current user interaction events. In some implementations, collaboration network graphs represent user-to-object relationships. In such implementations, the collaboration network graphs characterize activities performed by a user on an object. In some situations, collaboration network graphs characterize aspects of content object sharing conditions (e.g., “collab-in” shares) in addition to the aforementioned user-to-object characteristics. As used herein, sharing conditions are rules or other characterizations of circumstances as to whether or not a particular user can access a particular content object. Also as used herein, sharing conditions are rules or other characterizations of circumstances as to whether or not a particular group of users can access a particular content object.

Based at least in part on the then-current, actively-updated collaboration network graphs, a respective set of sharing boundaries associated with the graphs are generated (step 250). As shown, a set of sharing boundaries 124 might be generated for collaboration network graphs 122. The sharing boundaries might be generated in response to various events, such as receiving user interaction events, access requests, or content owner directives. When requests to access content objects are received, access is provisioned in accordance with the then-current sharing boundaries associated with the requests (step 260). In some cases, an outcome of the provisioning operation might be the application of one or more boundary adjustments 270 to the sharing boundaries 124. Boundary adjustments can be made on the basis of many types of changes in a collaboration network graph. As examples, boundary adjustments 270 can be made to include new users who newly access a content object. Or, boundary adjustments 270 can be made to include users at a second or third or Nth degree, or boundary adjustments 270 can be made to exclude some or all users at a second or third or Nth degree. Boundary adjustments 270 can be made to include only users who satisfy some rule or condition such as performance of a particular activity, or who are in some way correlated in a manner that characterizes a particular user as a user who is similar to the content object owner or similar to a user who has been the subject of a previous access request approval.

In response to an access request by a user that is outside of a then-current sharing boundary, an alert might be issued to the content object owner. If the owner approves access, the response of the owner will serve as a content owner directive that adjusts (e.g., expands) the sharing boundary to include at least the requesting user. In some cases, a boundary adjustment can be made to include users who are in some way correlated to users who have been previously approved. For example, if a particular user, who is two degrees separated from the content object owner, is provisioned access (step 260), then additional users who are two degrees separated might also be included within an adjusted sharing boundary.

As indicated in the figure, generation of the sharing boundaries (step 250) and provisioning of content object access based at least in part on the sharing boundaries (step 260) are characterized as dynamic operations 210. As such, sharing boundary management technique 200 and/or other herein disclosed techniques address the problems attendant to unintended access to content objects by consulting actively-updated collaboration network graphs to dynamically determine the sharing boundaries of the content objects.

One embodiment of a system, data flows, and data structures for implementing the sharing boundary management technique 200 and/or other herein disclosed techniques, is disclosed as follows.

FIG. 3 is a block diagram of a system 300 that implements techniques for dynamic generation of sharing boundaries. As an option, one or more variations of system 300 or any aspect thereof may be implemented in the context of the architecture and functionality of the embodiments described herein. The system 300 or any aspect thereof may be implemented in any environment.

FIG. 3 illustrates aspects pertaining to consulting actively-updated collaboration network graphs to determine the sharing boundaries of content objects. Specifically, the figure is being presented to show one embodiment of certain representative components and associated data structure and data flows implemented in a computing environment to facilitate the herein disclosed techniques. As shown, the components, data flows, and data structures are associated with a set of users (e.g., user 102 ₁, . . . , user 102 _(N)) that interact with each other and a set of content objects 106 managed at collaboration system 110. The components, data flows, and data structures shown in FIG. 3 present one partitioning and associated data manipulation approach. The specific example shown is purely exemplary, and other subsystems, data structures, and/or partitionings are reasonable.

As shown, system 300 comprises an instance of a collaboration server 310 operating at collaboration system 110. Collaboration server 310 comprises a message processor 312, a graph service 314, a sharing boundary generator 316, and a content access engine 318, which content access engine further comprises an alert generator 319. A plurality of instances of the foregoing components might operate at a plurality of instances of servers (e.g., collaboration server 310) at collaboration system 110 and/or any portion of system 300. Such instances can access each other (e.g., through a communications layer 320) and/or a set of storage devices 330 that store various information that facilitates the operation of the components of system 300 and/or any implementations of the herein disclosed techniques. For example, collaboration server 310 might facilitate access to shared content in content objects 106 by the users (e.g., user 102 ₁, . . . , user 102 _(N)) from a respective set of user devices (e.g., user device 302 ₁, . . . , user device 302 _(N)). The objects (e.g., files, folders, etc.) in content objects 106 are characterized at least in part by a set of object attributes 344 (e.g., content object metadata) stored at storage devices 330. Furthermore, the users are characterized at least in part by a set of user attributes 346 stored in a set of user profiles 338 at storage devices 330.

The users interact with the user interfaces (e.g., user interface 304 ₁, . . . , user interface 304 _(N)) of their user devices to send or receive various instances of messages 322 that are received or sent by message processor 312 at collaboration server 310. In some cases, certain agents or applications (e.g., a local content manager) operating at the user devices associated with the users might send or receive messages to or from collaboration server 310 without human interaction. One class of messages 322 are user interaction events that are invoked by the users when they interact with one another and/or with various content objects as facilitated by collaboration system 110. For example, users might log in to collaboration system 110 to interact with content objects they own or that are shared with them, and invite other users to collaborate on content objects and/or to perform other collaboration interactions. Any of the foregoing collaboration interactions or collaboration activities can be characterized as user interaction events.

The message processor 312 at collaboration server 310 can monitor messages 322 to detect user interaction events invoked by the plurality of users. Message processor 312 can codify certain interaction attributes 342 pertaining to the user interaction events in a set of event records 332 stored in storage devices 330. In some cases, message processor 312 will access user attributes 346 (e.g., user identifiers, etc.) stored in user profiles 338 and/or object attributes 344 (e.g., content object identifiers, etc.) stored in content objects 106 to facilitate populating the event records 332.

Event records 332 and/or any other data described herein can be organized and/or stored using various techniques. For example, event records 332 might be organized and/or stored in a tabular structure (e.g., relational database table) that has rows that relate various interaction attributes with a particular user interaction event. As another example, the event data might be organized and/or stored in a programming code object that has instances corresponding to a particular user interaction event and properties that describe the various attributes associated with the event.

In accordance with the herein disclosed techniques, interaction attributes 342 of event records 332 and/or other information at collaboration system 110 are accessed by a graph service 314 to form instances of collaboration network graphs 122. A set of graph data 334 stored at storage devices 330 codify the attributes of the collaboration network graphs 122. For example, graph data 334 codifies the entities (e.g., nodes) and entity relationships (e.g., edges) of the graphs and/or other entity attributes and entity relationship attributes (e.g., scores, weights, strengths, etc.) associated with the graphs.

Sharing boundary generator 316 accesses the then-current collaboration network graphs stored in graph data 334 and/or other information at collaboration system 110 to generate instances of sharing boundaries 124. As shown, a set of access rules 337 stored at storage devices 330 codify the attributes of sharing boundaries 124. A set of rules (e.g., rule base) such as access rules 337 or any other rules described herein comprises data records storing various information that can be used to form one or more constraints to apply to certain functions and/or operations.

For example, the information pertaining to a rule in the rule base might comprise conditional logic operands (e.g., input variables, conditions, constraints, etc.) and/or operators (e.g., “if”, “then”, “and”, “or”, “greater than”, “less than”, etc.) for forming a conditional logic statement that returns one or more results. More specifically, a set of access rules for a particular sharing boundary might comprise conditional logic operands that describe the characteristics of the entities (e.g., users) that are to be included within the boundary to distinguish such users from other users that are outside of the boundary. As such, sharing boundaries 124 as generated by sharing boundary generator 316 and/or any of the herein disclosed techniques and codified in access rules 337 are a logical representations of access permissions rather than fixed permissions used in other access models.

As later described in more detail, sharing boundary generator 316 might also access a set of sharing policies 336 to facilitate generation of sharing boundaries such as the shown sharing boundaries 124 _(K). In this example embodiment, the sharing policies define content object sharing constraints as may be specified by content object owners, and/or as pertaining to user groups (e.g., project group, functional department, etc.), and/or as pertaining to particular enterprises in the ecosystem, etc. In some cases, the sharing policies might define sharing constraints to achieve compliance with company confidentiality guidelines, privacy regulations, and/or other requirements.

User interaction events that request access to content objects are received at message processor 312 and forwarded to content access engine 318 for processing. Content access engine 318 will consult access rules 337 to facilitate processing of the access request. Specifically, the portion of access rules 337 pertaining to a selected instance of sharing boundaries 124 associated with the access request is consulted to determine whether access is allowed or denied. If access is allowed in accordance with the selected sharing boundary, then access permissions are issued in an instance of messages 322 to the requesting user. If access is denied in accordance with the selected sharing boundary, then access permissions are not provisioned to the requesting user.

In some cases, an access request alert may be issued by alert generator 319 to a content owner in response to a denied access request. If an alert response indicates that the requesting user is to be allowed access, then one or more access permissions are sent to the requesting user. In this case, the alert response may also invoke an update to one or more of sharing boundaries 124, access rules 337, and/or sharing policies 336. As can be observed, such alerts (e.g., alerts 306 ₁, . . . , alerts 306 _(N)) and responses (e.g., responses 308 ₁, . . . , responses 308 _(N)) can be received and submitted at user interfaces of user devices associated with the users (e.g., content owners) associated with collaboration system 110.

The foregoing discussions include techniques for constructing collaboration network graphs based at least in part on user interaction events at a collaboration system (e.g., step 240 of FIG. 2), which techniques and data are disclosed in further detail as follows.

FIG. 4 depicts a collaboration network graph generation technique 400 as implemented in systems that facilitate dynamic generation of sharing boundaries. As an option, one or more variations of collaboration network graph generation technique 400 or any aspect thereof may be implemented in the context of the architecture and functionality of the embodiments described herein. The collaboration network graph generation technique 400 or any aspect thereof may be implemented in any environment.

FIG. 4 illustrates aspects pertaining to consulting actively-updated collaboration network graphs to determine the sharing boundaries of content objects. Specifically, the figure is presented to illustrate one embodiment of certain steps and/or operations that facilitate constructing collaboration network graphs based at least in part on user interaction events at a collaboration system (e.g., step 240 of FIG. 2). A representative collaboration network graph generation scenario is also shown in the figure to illustrate an example application of collaboration network graph generation technique 400.

Collaboration network graph generation technique 400 commences by generating a set of feature vectors from a respective set of user interaction events (step 402). As illustrated, for example, a set of feature vectors 422 might be formed from the user interaction events 116 _(K). More specifically, each one of the feature vectors 422 will correspond to a respective one of user interaction events 116 _(K) and comprise a respective portion of interaction attributes 342 associated with the particular event. The portion of interaction attributes 342 serve as the “features” of feature vectors 422. Such features might include one or more user identifiers, one or more content object identifiers, a timestamp, and/or other user interaction event attributes.

Similarities between the feature vectors are calculated to form one or more clusters of user interaction events (step 404). For example, a set of clusters of user interaction events 424 can be formed from feature vectors 422. Any known machine learning techniques and/or clustering techniques can be applied to the feature vectors to form the clusters. The illustrated scenario indicates that the clusters can overlap (e.g., share one or more common features, feature vectors, or underlying user interaction events). In some cases (e.g., when more computing resources and/or time are available), generation of more clusters might be performed (“Yes” path of decision 406). Such additional clusters might be generated from an additional set of user interaction events (e.g., from an earlier historical period) or from a reapplication of a clustering technique (e.g., a different clustering technique, the same clustering technique with different constraints, etc.).

The one or more clusters of user interaction events are assigned group identifiers to identify a respective one or more user interaction groups (step 408) (e.g., once the “No” path of decision 406 is taken). As shown, the clusters of user interaction events 424 are assigned group identifiers (e.g., G_(K), G_(I), and G_(N)) to identify a respective cluster of interaction events. For each of the assigned user interaction groups, a collaboration network graph that corresponds to the group is constructed (step 410). A collaboration network graph characterizes the entities and entity relationships that comprise an interaction event group. There are many ways to generate a collaboration network graph and there are many ways to classify the entities and entity relationships that comprise an interaction event group.

Strictly as examples, a particular collaboration network graph might correspond to interaction group G_(K), where quantitative similarities of characteristics of the users and/or quantitative similarities among the relationships between the users constitute a group. Additionally, or alternatively, a particular collaboration network graph might be constructed to correspond to an interaction group that is formed on the basis of a constituent's membership in the same organization (e.g., membership in the marketing department, or membership in the engineering department, etc.). Additionally, or alternatively, particular collaboration network graph might be constructed to correspond to an interaction group that is formed on the basis of a constituent's membership in the same collaboration group as other constituents, and/or on the basis of a constituent's membership in the same object access group as other constituents, and/or on the basis of a constituent's membership in another object access group that is different from the former object access group, and/or an interaction group might be formed on basis of how many times a given user or set of users have accessed a particular content object or set of content objects.

Additionally, or alternatively, a particular collaboration network graph might be constructed to correspond to an interaction group that is formed on the basis of a relationship type (e.g., pertaining to a particular activity or permission), or on the basis of “closeness” (e.g., degrees of separation), or on the basis of similarities of activities, or on the basis of the type of invitations, and/or based on rights and/or permissions granted (e.g., permissions or invitations to edit, permissions or invitations to preview, etc.).

As illustrated, the collaboration network graphs for each user interaction group can be codified and stored as graph data 334.

The foregoing discussions include techniques for generating sharing boundaries that are associated with the collaboration network graphs (e.g., step 250 of FIG. 2), which techniques are disclosed in further detail as follows.

FIG. 5 presents a sharing boundary generation technique 500 as implemented in systems that facilitate dynamic generation of sharing boundaries. As an option, one or more variations of sharing boundary generation technique 500 or any aspect thereof may be implemented in the context of the architecture and functionality of the embodiments described herein. The sharing boundary generation technique 500 or any aspect thereof may be implemented in any environment.

FIG. 5 illustrates aspects pertaining to consulting actively-updated collaboration network graphs to determine the sharing boundaries of content objects. Specifically, the figure is presented to illustrate one embodiment of certain steps and/or operations that facilitate generating sharing boundaries that are associated with collaboration network graphs (e.g., step 250 of FIG. 2). A representative sharing boundary generation scenario is also shown in the figure to illustrate an example application of sharing boundary generation technique 500.

As shown, sharing boundary generation technique 500 is performed for each user in a collaboration system. Sharing boundary generation technique 500 commences by querying a set of graph data for the then-current collaboration network graph associated with a particular user (step 502). For example, graph data 334 might be queried to access a then-current collaboration network graph 522 that is associated with user 102 _(L). The sharing policy or sharing policies associated with the user are accessed (step 504). Such sharing policies, such as the representative sharing policy “One Degree” might be stored in sharing policies 336.

The sharing policies are applied to the collaboration network graph to generate a sharing boundary (step 506). As illustrated, a sharing boundary 124 _(K) associated with collaboration network graph 122 _(K) is generated in accordance with an instance of sharing policies 336 associated with user 102 _(K). Specifically, and as indicated by sharing boundary 124 _(K), the sharing policy or policies associated with user 102 _(K) might have specified that certain users that are one degree of separation (e.g., as determined by collaboration network graph 122 _(K)) from user 102 _(K) are to be allowed access to various content objects owned by user 102 _(K).

When the sharing boundary is determined, the attributes of the boundary are codified in a set of access rules (step 508). Access rules 337 earlier mentioned might store information that logically represents and serves to enforce the sharing boundary 124 _(K) associated with user 102 _(K) and collaboration network graph 122 _(K). Specifically, and as depicted in the representative access rule pseudo code 522, an access rule associated with sharing boundary 124 _(K) might allow access to any “user” characterized as having a distance (e.g., a degree of separation as calculated by a “dist ( )” function) that is “less than 2 degrees” from the content “owner”.

The foregoing discussions include techniques for provisioning access to content objects based at least in part on dynamically-generated sharing boundaries (e.g., step 260 of FIG. 2), which techniques are disclosed in further detail as follows.

FIG. 6 presents a content object access provisioning technique 600 as implemented in systems that facilitate dynamic generation of sharing boundaries. As an option, one or more variations of content object access provisioning technique 600 or any aspect thereof may be implemented in the context of the architecture and functionality of the embodiments described herein. The content object access provisioning technique 600 or any aspect thereof may be implemented in any environment.

FIG. 6 illustrates aspects pertaining to consulting actively-updated collaboration network graphs to determine the sharing boundaries of content objects. Specifically, the figure is presented to illustrate one embodiment of certain steps and/or operations that facilitate provisioning of access to content objects based at least in part on dynamically-generated sharing boundaries (e.g., step 260 of FIG. 2). A representative content object access provisioning scenario is also shown in the figure to illustrate an example application of content object access provisioning technique 600.

Content object access provisioning technique 600 commences by receiving a request from a user in a collaboration system to access a content object managed by the collaboration system (step 602). The received request is analyzed to identify the owner of the content object (step 604). In the accompanying scenario, user 102 _(K) is identified as the “owner” of the content object being requested. A then-current set of access rules that characterize the sharing boundary associated with the identified owner is retrieved (step 606). Such access rules might be retrieved, for example, by querying a set of access rules 337 stored at the collaboration system. Moreover, and as illustrated, such retrieved access rules might define the sharing boundary 124 _(K) associated with collaboration network graph 122 _(K).

The access rules that are retrieve are evaluated to determine the position of the requesting user access with respect to the sharing boundary represented by the rules (step 608). If the requesting user is within the sharing boundary (“Yes” path of decision 610), then access to the content object by the user is allowed (step 618). As can be observed in the representative content object access provisioning scenario, however, the requesting user (e.g., requesting user 622) might be outside of the sharing boundary (e.g., sharing boundary 124 _(K)).

When the requesting user is outside of the sharing boundary (“No” path of decision 610), an alert is issued to the content owner to allow or deny the access request (step 612). For example, an access request alert, such as depicted in an access request alert view 624, might be presented at the user interface 304 _(K) of the user device 302 _(K) of user 102 _(K). If the alert response (e.g., selecting the “Deny” radio button) from user 102 _(K) indicates that access is to be denied (“Deny” path of decision 614), then access to the content object is blocked (step 620). If the alert response (e.g., selecting the “Allow” radio button) from user 102 _(K) indicates that access is to be allowed (“Allow” path of decision 614), then the sharing boundary and access rules are updated (step 616) and access to the content object by the user is allowed (step 618). In some cases, if the alert response (e.g., selecting the “Allow Similar” radio button) from user 102 _(K) indicates that access is to be allowed to users that are similar to the requesting user (“Allow Similar” path of decision 614), then the sharing boundary and access rules are updated to expand the sharing boundary to include users that are similar to the requesting user.

There are many ways for delivering an alert. Strictly as an example, an alert can be delivered to the content object owner by raising a signal at the owner's smart phone (e.g., using an email or text alert or using or banner, or other type of app notification). As another an example, an alert can be delivered to the content object owner by raising a signal at the owner's smart watch.

As shown, an updated sharing boundary (e.g., sharing boundary 124 _(L)) associated with collaboration network graph 122 _(L) includes requesting user 622.
